Synesthesia and number cognition in children

Grapheme-color synesthesia, when achromatic digits evoke an experience of a specific color (photisms), has been shown to be consistent, involuntary, and linked with number concept in adults, yet there have been no comparable investigations with children. We present a systematic study of grapheme-color synesthesia in children aged between 7 and 15 years. Here we show that such children (but not children with phoneme-color synesthesia) experience involuntary difficulties in numerical tasks when digits are presented in colors incongruent with their photisms. Synesthesia in children may thus have important consequences for certain aspects of numerical cognition.     

Similarity relations among spoken words: The special status of rimes in English

This paper presents an analysis of the distribution of phonological similarity relations among monosyllabic spoken words in English. It differs from classical analyses of phonological neighborhood density (e.g., Luce &; Pisoni, 1998) by assuming that not all phonological neighbors are equal. Rather, it is assumed that the phonological lexicon has psycholinguistic structure. Accordingly, in addition to considering thenumber of phonological neighbors for any given word, it becomes important to consider thenature of these neighbors. If one type of neighbor is more dominant, neighborhood density effects may reflect levels of segmental representation other than the phoneme, particularly prior to literacy. Statistical analyses of the nature of phonological neighborhoods in terms ofrime neighbors (e.g.,hat/cat),consonant neighbors (e.g.,hat/hit), andlead neighbors (e.g.,hat/ham) were thus performed for all monosyllabic words in the Celex corpus (4,086 words). Our results show that most phonological neighbors are rime neighbors (e.g.,hat/cat) in English. Similar patterns were found when a corpus of words for which age-of-acquisition ratings were available was analyzed. The resultant database can be used as a tool for controlling and selecting stimuli when the role of lexical neighborhoods in phonological development and speech processing is examined.

Complexity Theory: Predictions Based on the Confluence of Science-Wide and Behavioral Theories

Views of behavioral and science wide complexity theories are briefly summarized. Theory-based predictions for human cognition and behavior based on both theories are advanced.
Streufert (in this special issue) has discussed the confluence of science-wide and behavioral complexity theory. Even though the former attempts to find common processes in all the sciences and the latter theory has, to date, limited itself to human behavior, there are many similarities in approach and in explanations of observed phenomena. Differences between the two theories are minor in comparison to their commonalities. Considering the many similarities, it may be useful to confirm (and possibly extend) behavioral complexity theory. A number of theorems, many familiar, some slightly modified, some new, will be provided at the end of this paper.     

Graphic Representations of Processing Structure: The Time-Event Matrix

Science-wide complexity theory presents strange attractors as lawful outcomes of nonlinear functions. The time-event matrices used by Streufert and associates to depict human information processing in complex task environments have similar characteristics. The use and construction of these matrices is described. The technique may be useful across sciences to depict the consequences of complex phenomena.     

What Does “Mind-Wandering” Mean to the Folk? An Empirical Investigation

Although mind-wandering research is rapidly progressing, stark disagreements are emerging about what the term “mind-wandering” means. Four prominent views define mind-wandering as (a) task-unrelated thought, (b) stimulus-independent thought, (c) unintentional thought, or (d) dynamically unguided thought. Although theorists claim to capture the ordinary understanding of mind-wandering, no systematic studies have assessed these claims. Two large factorial studies present participants (N = 545) with vignettes that describe someone's thoughts and ask whether her mind was wandering, while systematically manipulating features relevant to the four major accounts of mind-wandering. Dynamics explains between four and 40 times more variance in participants' mind-wandering judgments than other features. Our third study (N = 153) tests and supports a unique prediction of the dynamic framework—obsessive rumination contrasts with mind-wandering. Our final study (N = 277) used vignettes that resemble mind-wandering experiments. Dynamics had significant and large effects, while task-unrelatedness was nonsignificant. These results strongly suggest that the central feature of mind-wandering is its dynamics.     

Social identification and normative conflict: When student and educator learning norms collide

The current paper explores perceived norm conflict, social identification, and learning approaches in the applied context of higher education. Research has established the influence of identification with fellow students, and their perceived norms, on student approaches to learning. However, in the current paper, we argue that this model is not entirely ecologically valid and that students are not the only source of normative influence in the study context. In this first step to unpack these complex normative influences, we examine the next most‐proximal source of normative information—the educator. In essence, we explore the ways that the normative communications of a within‐field educator can also influence student learning approaches and the ways these two sets of normative effects may interact. Testing a sample of undergraduate students at Australian universities, we explore how students resolve conflicting intragroup norm sources. Findings suggest that, in line with previous literature, stronger identification with the field of study is associated with deep learning approaches, and this effect is moderated by perceived student norms such that the valence of the study norms can undermine or accentuate this effect. Novel results unpacking the effects of normative conflict suggest that this moderation effect is only present when educator norms are ambiguous and that, in instances of clearly conflicting normative messages, the identification main effect prevails. The implications and applications are discussed.     

The foundations of psychological understanding

In this paper, I review some recent submissions to Developmental Science that advance our understanding of psychological development. More and more submissions to the journal explore the origins of knowledge and, for psychological knowledge, such origins are multiple. Here I consider the contribution of mechanisms such as contingency detection, gaze following and gaze monitoring, social referencing and joint attention to emergent psychological understanding. I also consider infant understanding of goal-directed action, and the intimate connection between language acquisition and psychological development. The centrality of intention-reading skills to both language and social cognition is highlighted.     

The Nuts and Bolts of Behavioral Observation of Marital and Family Interaction

Despite considerable discussion in the literature about the advantages of observational research and the relative benefits of different coding systems and strategies, little is written about the actual implementation of this assessment strategy. This paper presents an overall framework as well as the essential components involved in collecting (selection of task, setting, unit of analysis, and coding system) and coding (transcribing, selecting and training coders, transforming data, and analyzing reliability) of observational data. To achieve success with observational methods, we emphasize several issues, including (a) the research question as the motivator for all decisions, (b) the interrelatedness of tasks, and (c) the implications of decisions early in the process for later stages of analysis and interpretation. Investigators are encouraged to communicate the details of their observational and coding procedures so that these methods are readily accessible for purposes of replication and comparison.     

Words can slow down category learning

Words have been shown to influence many cognitive tasks, including category learning. Most demonstrations of these effects have focused on instances in which words facilitate performance. One possibility is that words augment representations, predicting an across the-board benefit of words during category learning. We propose that words shift attention to dimensions that have been historically predictive in similar contexts. Under this account, there should be cases in which words are detrimental to performance. The results from two experiments show that words impair learning of object categories under some conditions. Experiment 1 shows that words hurt performance when learning to categorize by texture. Experiment 2 shows that words also hurt when learning to categorize by brightness, leading to selectively attending to shape when both shape and hue could be used to correctly categorize stimuli. We suggest that both the positive and negative effects of words have developmental origins in the history of word usage while learning categories. [corrected]
